No you're right, even a crazy bishonen fan like me finds it kinda creepy, especially the setting, I mean 13 brothers, wtf. >__> Also the MC is pretty much like every other doormat protag in Otome games, I really don't understand how people can be this submissive, plus it's sooo annoying to watch.
To be honest, none of the characters really appeal all that much to me. Maybe they'll grow on me later, I dunno but I do LOVE Subaru. He's so cute and adorable so I think I'll keep watching this series just for him. XD
